The facility corridor ended the way all Tower corridors ended.
With a choice pretending to be a doorway.
A set of double doors.
Metal frames set into stone walls.
Above them, a sign printed like an afterthought:
**THRESHOLD ACCESS — FLOOR 100 SECTOR**
Somin stared at the words.
Her hands were still shaking.
Jaehyuk could feel her pulse under his fingers.
Fast.
Angry.
Alive.
Mira stepped ahead.
She didn't look back.
She never did when the next thing could kill them.
The doors slid open.
Cold air hit Jaehyuk's face.
It smelled like metal and old blood.
The Tower's two skins met here.
Infrastructure.
And war.
The "sector" beyond wasn't a single hallway.
It was a wide basin of broken stone, half rebuilt with metal scaffolding.
A staging zone.
Not a safe zone.
A place where the Tower let humans organize themselves like ants.
And humans had.
Barricades.
Tents.
Supply crates.
People clustered in groups that looked too similar to a battlefield map.
Guild banners hung from improvised poles.
The Tower had always tolerated guilds.
Now it was giving them hooks to hang from.
Somin's breath hitched.
"Vanguard," she whispered.
Jaehyuk saw them.
A line of men and women in clean armor.
Not bloodstained.
Not desperate.
Controlled.
They stood at the center of the basin like they owned it.
And in a way, they did.
Because the Tower had left room for ownership.
A raised platform had been built near the sealed gate frame.
Not the Gate at 100.
A different frame.
A checkpoint.
A toll.
Vanguard soldiers stood on either side, spears and blades angled downward like a polite threat.
A signboard was bolted to the platform.
Handwritten.
Human.
But the ink was too neat.
Too straight.
It looked like the Tower had steadied the hand.
**FLOOR 100 ACCESS PERMIT REQUIRED**
**TOLL: 30 SHARDS / PERSON**
**SUPPORT CLASSES: REGISTERED**
Somin's face twisted.
"Registered," she said, like she might spit.
Mira's voice was low. "They're building a registry."
Jaehyuk stared.
The Tower loved registries.
Registries made people legible.
Legible meant manageable.
A Vanguard officer stood near the signboard.
His posture was relaxed.
His sword was clean.
His eyes were not.
He spotted Mira first.
Then Jaehyuk.
Then Somin.
His gaze lingered on Somin like he'd just found a rare item.
Jaehyuk stepped half a pace so his body blocked that look.
The officer smiled.
Not friendly.
Professional.
"Yun Jaehyuk," he called.
Somin stiffened.
Mira didn't.
Mira had already decided what kind of violence this would require.
Jaehyuk's voice came out flat. "You know my name."
The officer tapped the signboard.
"There are lists," he said.
Of course there were.
Mira's gaze swept the basin.
She counted.
Vanguard had too many people here.
Too much organization.
Too much supply.
They had arrived before everyone else.
Or they had been allowed to.
Somin whispered, "How did they get up here?"
Jaehyuk didn't answer.
Because he could see the real answer in the air.
A bracket notice flickered near the checkpoint.
Not in his vision.
In the world.
Half-visible.
Like a watermark.
[ACCESS: AUTHORIZED]
Vanguard.
Authorized.
The Tower was letting them build scaffolding.
Just like Iteration 6 said.
The officer's smile widened.
"Pay the toll," he said. "Or leave. Those are the rules."
Mira's sword moved.
Not a swing.
A small shift that made the air feel sharper.
"We don't pay thieves," Mira said.
The officer didn't look at her sword.
He looked at her face.
As if he was memorizing it.
"As you like," he said.
Jaehyuk stepped forward.
He didn't go to the platform.
He went to the supply crates.
To the people behind them.
To the logistics.
Because this wasn't a duel.
This was a system.
He walked along the basin edge.
Eyes scanning.
Routes.
Weak points.
Airdrops.
He saw healers.
Clustered.
Guarded.
He saw permits.
Paper slips with stamps.
He saw a small queue of exhausted climbers handing over shards like beggars buying permission to breathe.
Somin's jaw clenched.
"They can't do this," she whispered.
Mira's voice was calm.
"They can," Mira said. "Because nobody stops them."
Jaehyuk stopped near a support tent.
Inside, a healer—someone Somin would have called junior—was patching a man's ribs with shaking hands.
A Vanguard soldier watched her.
Not helping.
Monitoring.
The soldier's gaze flicked to Somin.
Jaehyuk felt it.
He felt the way eyes moved toward her now.
Like her tag was a scent.
Mira noticed too.
Her stance shifted.
A subtle repositioning.
She placed herself so anyone approaching Somin would have to pass her blade.
Jaehyuk inhaled.
He looked at the toll signboard again.
Thirty shards.
That was enough to hurt.
Not enough to stop Vanguard.
This wasn't profit.
It was control.
He turned to Mira.
"Don't fight them here," he said.
Mira's gaze snapped to him.
"Why not?"
"Because that's what they want," Jaehyuk said.
Mira's eyes narrowed.
"And what do you want?"
Jaehyuk looked past her.
At the permit table.
At the stamps.
At the ledger.
At the crates.
At the men who never bled.
"I want to make the toll worthless," he said.
Somin blinked. "How?"
Jaehyuk didn't answer.
He moved.
Quiet.
Fast.
Not running.
Walking like he belonged.
He approached the permit platform from the side.
He didn't look at the guards.
He looked at the stamp.
A heavy metal stamp with Vanguard's insignia.
The officer watched him.
Curious.
Suspicious.
Jaehyuk reached into his coat.
He pulled out the paper transcript from the white room.
The officer's eyes widened a fraction.
Not because of the paper.
Because the paper was too clean.
Too "system."
Jaehyuk held it up.
"I need a permit," he said.
The officer smiled.
"Thirty shards," he said.
Jaehyuk nodded.
He placed the transcript on the table.
It wasn't a permit.
It wasn't even related.
But the Tower liked documents.
And the Tower was listening.
Jaehyuk spoke loud enough for the people in line to hear.
"Fine," he said. "Register me."
Somin's head snapped toward him.
Mira's sword lifted.
A warning.
Jaehyuk didn't look back.
He let them think he was surrendering.
Because he wasn't.
The officer leaned forward.
His gaze flicked to the paper.
Then to Jaehyuk's face.
"You're smart," the officer said softly. "Be smart. Pay the toll. Sign the ledger. Don't make this complicated."
Jaehyuk's voice was calm.
"I'm not making it complicated," he said.
He placed thirty shards on the table.
A clean stack.
Hard-earned.
Not because he cared.
Because he wanted the people watching to see him do it.
He wanted them to think he was buying time.
The officer reached for the stamp.
Jaehyuk's fingers moved.
Not fast.
Precise.
He slid the transcript half an inch.
So the stamp would land on it.
Not a permit.
A system transcript.
A document the Tower cared about.
The officer stamped.
Thud.
Ink.
The Vanguard insignia printed onto the transcript.
For a breath, nothing happened.
Then the air changed.
A low hum ran through the basin.
Not the war.
The Tower.
A bracket notice printed in the world, visible to everyone.
[DOCUMENT AUTHORITY CONFLICT DETECTED]
The officer froze.
Mira's eyes sharpened.
Somin's breath caught.
The Tower didn't like conflicting authorities.
Vanguard had just put its stamp on the Tower's paper.
Jaehyuk's voice stayed calm.
"Looks like you just registered yourself," he said.
The officer's face tightened.
The guards shifted.
Too late.
Another notice printed.
[EXTERNAL OPERATOR: VANGUARD][STATUS: UNVERIFIED]
A wave of murmurs ran through the waiting line.
People stepped back.
Not from Vanguard.
From the idea that Vanguard's authority could be questioned.
The officer's smile broke.
Just for a second.
Anger slipped through.
He leaned close.
His voice dropped.
"You think this is clever," he hissed. "You think the Tower is going to help you."
Jaehyuk met his eyes.
"No," Jaehyuk said. "I think it's going to punish you."
The hum deepened.
The platform lights flickered.
The permit table shuddered.
The stamp grew hot under the officer's hand.
He yanked it back.
Too late.
The Tower printed:
[PERMIT SYSTEM: TEMPORARILY DISABLED]
A sharp sound went through the basin.
Not a bell.
A denial.
The toll signboard cracked down the middle.
Ink bled.
The words blurred.
People gasped.
Vanguard guards stepped forward.
Mira moved.
Her sword flashed.
Not to kill.
To cut the air.
To draw a line.
"Back," Mira said.
Her voice was not loud.
It didn't need to be.
The guards stopped.
Not because they respected her.
Because they felt something in her.
The future king.
The kind of aura people pretended wasn't real.
Somin exhaled shakily.
She grabbed Jaehyuk's sleeve.
"Are you insane?" she hissed.
"Yes," Jaehyuk said.
Then, quieter:
"Keep moving."
They turned.
They walked through the basin while Vanguard shouted behind them.
The officer barked orders.
Soldiers surged.
But the permit checkpoint was down.
The toll was gone.
For now.
Jaehyuk knew "for now" was a lie the Tower loved.
Mira's gaze swept for exits.
Routes.
Cover.
Somin stayed between them.
Not because she was weak.
Because she was the center.
The Tower's priority.
And now Vanguard's.
A man stepped onto a second platform at the far side of the basin.
Taller.
Broader.
Armor that looked ceremonial.
A cape.
A hero costume.
The crowd quieted.
Because everyone knew his face.
Kang Dohyun.
The man called hero.
He lifted a hand.
And the basin fell silent like a church.
Jaehyuk felt his jaw tighten.
Dohyun smiled.
Warm.
Practiced.
The smile of a man who had learned that image was stronger than steel.
"My friends," Dohyun called.
His voice carried.
Not because he shouted.
Because Vanguard had speakers.
Because the Tower had let them.
"We have reached a threshold," Dohyun said. "A dangerous place. A place where the Tower's rules… change."
Murmurs.
Fear.
Hope.
Dohyun's gaze swept the crowd.
Then it landed on Jaehyuk.
It didn't linger.
It didn't need to.
Jaehyuk felt it like a hook in his ribs.
"To protect the many," Dohyun continued, "we must regulate access. We must register support classes. We must ensure the weak are not exploited."
Somin's mouth twisted.
Mira's blade trembled once.
Dohyun smiled wider.
"The permit system has been… disrupted," he said gently. "A misunderstanding. We will restore order."
His voice softened.
"As always, Vanguard will bear the burden."
The crowd murmured approval.
Jaehyuk felt disgust rise.
Dohyun's greatest weapon wasn't his guild.
It was people's desire to believe in a hero.
Dohyun lifted a sheet of paper.
A notice.
Not a bracket notice.
Human.
But it glowed faintly, like the Tower had approved it.
Dohyun's voice turned colder.
"But there are those who would endanger you. Those who would sabotage stability for personal agendas."
His gaze swept again.
This time it paused on Somin.
Just long enough.
Somin felt it.
She stiffened.
Jaehyuk's hand tightened around her wrist.
Dohyun smiled.
"Therefore," he said, "Vanguard issues a public bounty."
The basin held its breath.
Dohyun's voice rang.
"Bring me Lee Somin alive."
Somin's blood went cold.
Mira's sword snapped up.
Jaehyuk's mind went very quiet.
Dohyun continued, like he was announcing a festival prize.
"Reward: one hundred shards. Priority permits. Protection under Vanguard."
The crowd erupted.
Not in outrage.
In calculation.
People's eyes turned.
Searching.
Hunting.
Somin's voice came out thin.
"Jaehyuk…"
Jaehyuk didn't look at her.
He stared at Dohyun.
Dohyun's smile stayed warm.
Heroic.
As if he was saving the Tower.
As if Somin was a resource to be secured.
Jaehyuk's thumb tapped once.
He stopped.
He tightened his grip on Somin's wrist.
Not to control.
To promise.
Mira stepped forward.
Her voice cut through the noise.
"Anyone who comes for her," Mira said, "dies."
Dohyun's gaze flicked toward Mira.
His smile didn't change.
But his eyes did.
They looked pleased.
Like the Tower had just handed him a lever.
A bracket notice printed in Jaehyuk's vision.
[EXTERNAL THREAT LEVEL: ESCALATING][NONCOMPLIANT SUPPORT: HIGH PRIORITY]
The Tower and Vanguard wanted the same thing.
And for the first time since Floor 1, Jaehyuk realized the simplest truth in the Tower:
When two monsters agree, someone human pays.
